INDUCTION APPARATUS.

SPEGIFICATION-forming part of Letters Patent No. 509,400, dated November 2B', 1893.

Application filed November 28. 1892 Serial No. 452.923. (No modeL) To allwhom iii may concern:Y

Be it known Athat I, MARTIN RosE vRUBLE, a citizen 'of 1 the United States, residing at Newark, county of Essex, andState off New J ersey,have invented certain`new` and useful Improvemepts in Induction Apparatus; and I do hereby declare the following to be a'full, clear, and exact description of the invention, 4such as will enable others skilled in the. art to which it appertains to make and use the same, reference beinghad to theaccompanyingdrawings, and to letters of reference marked thereon, which form a part of this specification. The object of my invention is the constructionbf a new and useful induction apparatus,

matters may be sucked up and discharged by means of the passage of a current ot air.

In the drawings, similar letters indicate similar parts throughout the diterent views.`

Figure 1. is a side view of the'improved induction apparatus, with certain portions broken away. Fig. 2. is across section on the line -x of Fig. 1. and Fig. 3, a cross section on the line y--y Fig. 1.

In said drawings, a represents an elliptical and conical case or shell, one end of which is closed by a partition b and the other end terminating in a pipe or discharge tube c. Entering this case rt is an air pipe or tube z'-, leading lrom a blower or other suitable air forcing apparatus. One end of this pipez' terminates some distance from the end of pipe c and beyond the end of case a; the diameter of the pipe or tube i is less than thedameter of the discharge c. Entering the closed end b of case o are the suction tubes or the air, gases,dust, shavings or similar matters to be removed, are situated.

Between the walls of the case a. and tube i arel placed partitions m, thus dividing the space in said case c into two separate com partmcnts into which the tubes g and 7L, enter. The diameters of the dust conveying partmcnt at the point where the tubes enter, but at thc discharge end of said compartment or at the point where the compartment enters the tube c, the areas ofthe compartment and of the tubes q and h, (combined) are approximately equal. The partition b forms an air' The operation is as follows: Airis forced into the tube i by means of a blower or any other vsuitable means in the direction indi- Y cated by the arrows."- The passage of the air from the end or outlet 4et' said tube into the tubo c, creates a vacuum or suction in the latter and also inthe case o, and tubes g-and h, thereby generating a strong current in said tubes, in the direction indicated by the arrows that is to say toward the discharge "end of the tube c.` The intermingling of the currents set up in the tubes g and h, within A the case a is prevented by the partitions m',

and each current passes separately through the case a. into tube c. This construction increases the efliciencyof the suction within the tubes g and h greatly since there are no cross currents, set up in the tubes or within the case a where the tubes terminate, to interfere with or lessen the suction.

It will be understood that there may be arranged a series of one or more dbris conveying tubes g or h, (two being shown in the drawings sim ply for example) and that each 2 tube may lead to separate points to -remcve or carry one or more matters into the discharge c. It is also to be understood that the form of the case a is made ellipsoidal simply for convenience and that any form of case may be used provided the same is Haring or 'bell shaped; the greatest diameter being at the point oflentrance of the suction tubes and the smallest at the point of discharge into tube c.

` Having-thus described my invention. what I claim as new, and desire to secure by Letters Patent, is-

fi, Haring case a and discharge tube c, with the suction tubes g and h entering the closed end of said case a and designed to convey gas, dust, shavings, tbc., to saidcase a and g5 vwith the partitions 'm separating said case a into separate compartments into each of4 which one of said tubes g` or h enters, substantially'as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 1st day` of October, .1892. i
